If you just want something works, search for delete folder SHFileOperation
and you will find plenty of code that actually work.

If you want to correct your error check the return value of SHFileOperation
and compare it to the possible return values listed in SHFileOperation's
documentation in MSDN

In addition, memset(szBuffer, 0, sizeof(szBuffer)); may not empty the whole
buffer if your program is compiled in a Unicode configuration. TCHAR is 2
bytes in a Unicode configuration

I am not sure why you add "\\\\?\\" to the front of the folder path. Use
PathFileExists to check if you are deleting a nonexistent folder.

Why is this functionality so difficult to do and find described
online?

If you know the exact steps - I mean the EXACT code - for deleting a
folder (and yes that means it can have files and folders within it
please let me know how it's done EXACTLY. My code isn't working

If you're just going to do the usual newsgroup thing where you give me
a riddle, a tip that leads nowhere, or a fragment of an answer please
hit the back button now. I need an actual answer that actually works.

BTW: Here's what I did and it fails:

// Delete the contents of the driver's backup folder
SHFILEOPSTRUCTW info;
memset(&info, 0, sizeof(info));
info.wFunc = FO_DELETE;
info.fFlags = FOF_NOCONFIRMATION | FOF_SILENT;

TCHAR szBuffer[2048];
memset(szBuffer, 0, sizeof(szBuffer));
_tcscpy(szBuffer, _T("\\\\?\\"));
_tcscat(szBuffer, (LPCTSTR)strFolderToDelete);

info.pFrom = szBuffer;
if (0 != SHFileOperationW(&info))
